TPUs and micro pellets for conveyor belts

Together with its strategic partner Bayer MaterialScience, the natural fibre-reinforced Desmovit DP R Eco NF has been developed. The goal was to develop a material with good mechanical properties, which has weight advantages in comparison to glass fibre-reinforced thermoplastic polyurethane. The newly developed material comes with a weight optimisation of 8 %. Due to its high firmness, Desmovit DP R Eco NF is well suited for components and assemblies with low wall thickness. A further advantage is its fracture behaviour. The material forms no sharp edges when breaking, so that the risk of injury is reduced to a minimum. Therefore it can be perfectly used for the production of sporting goods. Currently, the material is offered with a 10 % or 20 % natural fibre reinforcement. The company already announced plans to develop a series with a bio-based reinforcement combined with a bio-based TPU. This would lead to a bio-based ratio of above 50 % of the material.[image_0]Since 2012 geba produces micro pellets with particle sizes of <?500 µm and with very good flow and melting properties. The gebamic pellets enable a dust-free processing and are an ideal alternative to powder. Applications are, for example, conveyor belts, rotational moulding, slush skins and fabric coatings in the automotive sector. The pellets are suitable for all applications that depend on exact dosages, such as in the micro-injection moulding process or in the production of colour- and functional batches. geba has recently developed a special gebamic TPU grade for conveyor belt applications and will present it as a premiere at K 2013. The grade is available in 90 Shore A, hardness can be adjusted to customer's needs. Additionally there are gebamic pellets available that are approved for food applications and are therefore ideally suited for conveyor belts in food production and packaging.Hall 5, stand A47
